NA 370z on e85

Plus this was done on an OE ECU using a flash just like any tune for the Z. Just modified fuel and timing tables plus some other in the weeds stuff. 02 sensors react at the same rate as they did before on 100% gasoline, you just tune in the 30% loss in flow due to the E85. It's the same as tuning for meth injection. You have a tune. you run meth. you find the baseline change, and tune for it.

As for praying about the octane content. as long as you fill up consistently with the same blend of E85, and your tune isn't trying to ride the bleeding edge of performance, it's less dangerous than tuning for 91/93, if you know what you are changing and why. You have the same chance of getting poor gasoline as poor E85.

This article is assuming 100% E85, thus all the references to changing fuel system components. I'm just using it for subjective purposes, being that I'm implying a blend of E85 and gasoline to make no changes to the fuel system.

I'm not trying to start a pissing match, just curious on the subject, and why this approach would or wouldn't work for our platform.
